The setup shown is used to work out a value for the enthalpy of combustion of butan-1-ol. The mass of $1.00\,\text{cm}^3$ of water is $1.00\,\text{g}$. Before heating, the mass of burner $+$ butan-1-ol is $58.34\,\text{g}$, and after heating it is $57.85\,\text{g}$. The water starts at $17.6\,^{\circ}\text{C}$ and finishes at $41.1\,^{\circ}\text{C}$. Butan-1-ol has $M_r = 74$. Using these data, what value, to three significant figures, can be found for the enthalpy of combustion of butan-1-ol?
- A$-114\,\text{J mol}^{-1}$
- B$-17.2\,\text{kJ mol}^{-1}$
- C$-2600\,\text{kJ mol}^{-1}$
- D$-4540\,\text{kJ mol}^{-1}$
